These springs are designed to work with OEM shocks but will benefit from using high performance shocks such as Tokico also found on the Fab9Tuning site.
Progress specifies only certified high-tensile SAE spring wire materials. Our springs are cold-wound on modern CNC coiling machines, then stress relieved, pre-set, and shot-peened for maximum durability.
